This discovery process populates the ServiceNow Configuration Management Database (CMDB) with detailed information about MemoryDB nodes and clusters, enabling better visibility and management of your cloud database assets. Show full answer Show less To ensure accurate discovery, it is recommended to use the latest Discovery and Service Mapping Patterns application from the ServiceNow Store, as new patterns are released quarterly. ## Prerequisites * **AWS Credentials:** Configure AWS Credentials on your ServiceNow instance to authenticate API calls. * **AWS Service Account:** Set up a valid AWS service account within ServiceNow for discovery operations. * **User Permissions:** Ensure the user account has permissions to execute AWS MemoryDB for Redis API calls, specifically `DescribeClusters` and `ListTags` actions. * **Discovery Schedule:** Create and configure a Cloud Discovery schedule in ServiceNow, setting the discovery type to Cloud Discovery. * **REST API Permissions Verification:** Use the Cloud Discovery patterns spreadsheet to verify necessary permissions and pattern details. Testing of AWS REST APIs can be done using tools like Postman. ## Data Collected During Discovery When running the Amazon AWS MemoryDB pattern, the following key data is collected and stored in the CMDB: * **Cloud Database \[cmdbciclouddatabase\]:** Information about individual MemoryDB nodes, including their Amazon Resource Name (ARN), name, fully qualified domain name (FQDN), TCP port, and database type set to *memorydb*. * **Cloud Database Cluster \[cmdbciclouddbcluster\]:** Details about MemoryDB clusters such as cluster ARN, name, FQDN, and TCP port. ## CI Relationships and References The pattern automatically establishes relationships to support comprehensive discovery and CMDB integrity: * Clusters contain multiple MemoryDB nodes (*Cluster of::Cluster* relationship). * Clusters are hosted on AWS Datacenters (*Hosted on::Hosts* relationship). * References link cluster records to key-value tag data within the CMDB. ## AWS Tag Discovery The discovery pattern collects AWS tags associated with MemoryDB clusters and stores them in the **Key Value \[cmdbkeyvalue\]** table, associating each tag with the corresponding Cloud Database Cluster. This allows tagging metadata to be leveraged for filtering, reporting, and operational management within ServiceNow. ## Benefits for ServiceNow Customers * Automated and accurate discovery of AWS MemoryDB for Redis resources ensures your CMDB reflects your cloud environment. * Integration of cluster and node-level data with relationships improves asset transparency and impact analysis. * Tag collection enables enhanced categorization and management of MemoryDB resources. * Supports compliance and operational efficiency by providing up-to-date cloud database information. The ® Discovery application uses the Amazon AWS MemoryDB pattern and extensions to find AWS MemoryDB for Redis. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store. ## Request apps on the Store {#aws-memorydb-discovery__id_i2h_mj1_bvb} Visit the [ServiceNow Store](https://store.servicenow.com/sn_appstore_store.do#!/store/home) to view all the available apps, and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the [ServiceNow Store version history release notes](https://www.servicenow.com/docs/r/store-release-notes/sn-store-release-notes.html).{#aws-memorydb-discovery__inline-send-to-store} ## Prerequisites {#aws-memorydb-discovery__section_prj_nrr_v5b} Configured AWS Credentials : On your instance, configure credentials of type AWS Credentials. For more information, see [Access setup for AWS service accounts](https://www.servicenow.com/docs/aAgx5XgcWrd7JqD0NUDL9Q "Cloud Discovery and Cloud Provisioning and Governance need access to resources in the Amazon Web Services (AWS) service accounts. Learn about different methods of configuring such access."). Configured Cloud service account : Configure the AWS service account valid in the ServiceNow instance. For more information, see [Set up AWS service accounts.](https://www.servicenow.com/docs/Ne9_EUn4j5vmLXgoJrnYnQ "Create and configure cloud service accounts at ServiceNow AI Platform for the corresponding Amazon Web Services (AWS) service accounts.") Configured user permissions to execute the list AWS MemoryDB for Redis API calls : Provide the user permission to run the following API: * https://memory-db.{region}.amazonaws.com?Action=DescribeClusters\&ShowShardDetails=true * https://memory-db.{region}.amazonaws.com? Action=ListTags\&ResourceArn={arn} {#aws-memorydb-discovery__ul_wjd_gmr_svb} : For more information, see [Amazon AWS Cloud components discovery using patterns.](https://www.servicenow.com/docs/NFaTlkGaSxMWb2bQPsCnCA "Discovery and Service Mapping Patterns uses patterns to discover components of the Amazon AWS Cloud deployment during horizontal discovery. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.") Configured Cloud Discovery schedule : Create a cloud application schedule for discovering AWS datacenters. Set Discovery to Cloud discovery. For more information, see: [Create schedules for discovering cloud resources in Cloud Discovery Workspace](https://www.servicenow.com/docs/AGFiYHPbJImTnaawWg~_hQ "Create schedules for discovering cloud resources based on the discovery method that you choose: service accounts or IP ranges. The discovery schedule defines the various settings for the cloud discovery.") ## Verify the REST API permissions {#aws-memorydb-discovery__id_ysv_22b_f1c} Download the [Cloud Discovery patterns spreadsheet](https://downloads.docs.servicenow.com/resource/enus/api/servicenow-discovery-patterns-api-details.xlsx) so you can grant user permissions required for running the Discovery patterns. In addition to permissions, the spreadsheet also includes useful information such as pattern names, types, CI Classes, and links to vendor documentation. New patterns are available quarterly, so check periodically to be sure you have the latest version of the spreadsheet.{#aws-memorydb-discovery__cloud-discovery-api-ph-short-prereq} Note: You can test the AWS REST APIs using Postman API platform. For more information, see the [How to test AWS REST API using POSTMAN \[KB0782183\]](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0782183) article in the Now Support Knowledge Base. ## Data collected during AWS MemoryDB for Redis horizontal discovery {#aws-memorydb-discovery__section_md4_mqh_w5b} Discovery populates the data in the CMDB when running the Amazon AWS MemoryDB pattern. {#aws-memorydb-discovery__table_olj_wwb_x5b__entry__2} | Field | Description | |-|-| | Object ID \[object_id\] | The Amazon Resource Name of a single node in the cluster. | | Name \[name\] | The name of a single node in the cluster. | | Fully qualified domain name \[fqdn\] | The Fully Qualified Domain Name of each node in the cluster. | | TCP port(s) \[tcp_port\] | The TCP port that a single node in the cluster is getting traffic from. | | Type \[type\] | The type of database.
